Title: Ink cartridge and inkjet recording device
Inventor: KATAYAMA NAOKI
IPC: B41J2/175
Filed: 2003-04-16
Abstract: <P>PROBLEM TO BE SOLVED: To provide an ink cartridge and an inkjet recording device which can realize stable ink discharging even when an ink remaining amount of a storing part changes.  <P>SOLUTION: A bag body 55 shrinks when the ink is consumed, and the interior of a liquid chamber 41a becomes a decompression state by the volume. When it becomes the decompression state, the atmosphere is introduced into the liquid chamber 41a through a communication opening 73 from a gas chamber 70. An interface S is lowered corresponding to the volume of shrinkage. The interface S is always located higher than a lower end of the communication opening 73 with respect to the vertical direction. Therefore, a back pressure which acts to the ink held in a recording head unit 3 is made constant until the bag body reaches an ink empty. A good recording characteristic can be realized accordingly. It is detected by an optical sensor 8 that the interface S becomes lower than a predetermined position (ink empty position).  <P>COPYRIGHT: (C)2005,JPO&NCIPI
